Abstract

The invention discloses a wire enamel with high temperature resistance. The wire enamel is characterized by being made of the following raw materials by weight part(kg): 12-15 of nylon 12, 10-12 of polyamide resin, 10-12 of asphalt, 2-4 of sepiolite, 6-9 of vermiculite, 1-2 of an anti-aging agent NBC, 1-2 of 2-methylimidazole, 10-14 of phenolic resin, 3-5 of trimellitic anhydride, 3-5 of isocyanate, 3-4 of polyisobutene, 12-15 of polyvinyl acetate, 7-9 of an assistant, 80-90 of m, p-cresol, and 100-120 of dimethylbenzene. The technological process is short, the operation is simple, the environment-friendly practicability is strong, and the storage is stable.

Description

technical field [0001] The invention relates to a wire enamel, in particular to a wire enamel with high temperature resistance and a preparation method thereof. Background technique [0002] Enameled wire is a kind of electrical material. It processes a thin layer of high-strength insulating layer on the surface of a round copper wire to insulate it from the outside world. According to the specifications, it can be processed into a wool thread thinner than a hair, and a yarn-covered thread as thick as a thumb. Enameled wire has good insulation effect and waterproof ability. It is widely used in electrical appliances, such as motors, generators, water pumps, electromagnets, electric welding machines, household appliances, wireless communications, speakers, telegraphs, transformers, etc. Enameled wire enamel is a necessary insulating material for the production of enameled wire. Enameled wire enamel requires good adhesion, mechanical strength, insulation performance, heat re...
